बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding India's LVM3 launch vehicle: 1. LVM3 is a three-stage launch vehicle, with the first stage comprising two solid strap-on boosters. 2. It is primarily designed to launch heavy communication satellites into Geostationary Transfer Orbit (GTO). 3. NewSpace India Limited (NSIL) is the commercial arm of ISRO responsible for providing end-to-end launch services globally. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: D
Statement 1 is correct: LVM3 (Launch Vehicle Mark-3), formerly GSLV Mk III, is a three-stage launch vehicle. The first stage consists of two S200 solid strap-on boosters. The second stage is a liquid core stage (L110), and the third stage is a cryogenic upper stage (C25). Statement 2 is correct: LVM3 is India's heaviest operational launch vehicle, primarily designed to launch heavy communication satellites into Geostationary Transfer Orbit (GTO) and also capable of launching payloads into Low Earth Orbit (LEO) for missions like Gaganyaan. Statement 3 is correct: NewSpace India Limited (NSIL), a Public Sector Undertaking under the Department of Space, is indeed the commercial arm of ISRO, mandated to transfer ISRO-developed technologies to Indian industries and market ISRO's launch services and space-based products globally.
2. With reference to India's space launch vehicles and propulsion technology, consider the following statements: 1. The LVM3 launch vehicle utilizes an indigenously developed cryogenic upper stage. 2. Cryogenic engines use liquid oxygen and liquid hydrogen as propellants, offering higher specific impulse compared to solid or Earth-storable liquid propellants. 3. The Polar Satellite Launch Vehicle (PSLV) is known for its capability to launch satellites into Geostationary Transfer Orbit (GTO) using its cryogenic upper stage. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: A
Statement 1 is correct: LVM3 (GSLV Mk III) uses the C25 cryogenic upper stage, powered by the CE-20 cryogenic engine, which was indigenously developed by ISRO. Statement 2 is correct: Cryogenic engines use propellants (liquid oxygen as oxidizer and liquid hydrogen as fuel) at extremely low temperatures. This combination provides a very high specific impulse, meaning more thrust per unit of propellant, making them highly efficient for upper stages. Statement 3 is incorrect: PSLV (Polar Satellite Launch Vehicle) does not have a cryogenic upper stage. It primarily uses solid and Earth-storable liquid propellants. PSLV is primarily used for launching satellites into Low Earth Orbit (LEO) and Sun-Synchronous Orbit (SSO), while GSLV/LVM3 is designed for Geostationary Transfer Orbit (GTO) missions.
3. Which of the following is NOT a recent initiative or reform aimed at fostering private sector participation and commercialization in India's space sector?
- A.Establishment of NewSpace India Limited (NSIL) as a Public Sector Undertaking under the Department of Space.
- B.Creation of the Indian National Space Promotion and Authorization Centre (IN-SPACe) as an autonomous nodal agency.
- C.Mandating ISRO to exclusively handle all satellite manufacturing and launch operations for domestic and international clients.
- D.Liberalization of the geospatial data policy to allow private entities to generate and utilize geospatial data.
उत्तर देखें
सही उत्तर: C
Statement C is incorrect. Recent reforms in India's space sector are specifically aimed at *reducing* ISRO's exclusive role and *promoting* private sector involvement across the entire spectrum of space activities, including satellite manufacturing, launch operations, and providing space-based services. The establishment of NSIL (Option A) is to commercialize ISRO's technologies and services, and IN-SPACe (Option B) acts as a single-window agency to facilitate private sector participation. The liberalization of the geospatial data policy (Option D) also encourages private entities. Therefore, mandating ISRO to exclusively handle all operations contradicts the spirit of these reforms.
